Define torque current characteristics of DC machine
Answers
Explanation:
The torque in case of a dc series motor is proportional to the square of the armature current. ... Saturation means although the current through the winding increases, the flux produced remains constant. Hence after the saturation, the characteristics take the form of the straight line as flux becomes constant.
Answer:
Torque and armature current characteristics: In case of a series motor, the series field winding is carrying the entire armature current. Flux produced is proportional to the armature current. The torque in case of a dc series motor is proportional to the square of the armature current.
When the current-carrying current is placed in the magnetic field, a force is exerted or it which exerts turning moment or torque F x r. ... This torque is produced due to the electromagnetic effect, hence is called Electromagnetic torque.
